Hellkite Dominator

Flying, Haste, Trample
Whenever Hellkite Dominator enters the battlefield, it deals damage equal to the number of dragons you control to each non-dragon creature on the battlefield. Hellkite Dominator gets +1/+1 for each creature destroyed this way.
Slow to stir, the most powerful Hellkites still slumber between the Shards, waiting for a time to rise again.
